Yamaha CP33 Review

The Yamaha CP33 is another digital piano that price as the Yamaha P155, so what are the differences? Which one should you get?

Well, there are pros and cons to both. For example, the Yamaha CP33 is more of a stage piano while the Yamaha P155 is more of a home piano

I will break these down to give you a better idea of what to get. You might want to take a few days before deciding as well. After all, spending a grand is never an easy decision…unless you’re rich.

 The Yamaha CP33 is for:


    Great interface for stage pianos

    Impressive grand piano sound and keys

    39.7 pounds (a bit heavy, but somewhat portable for performers)


No speakers, although most stage pianos do not have speakers

Yamaha CP33: Feel and Sound

First thing you’ll notice is that the Yamaha CP33 technically uses the same keyboard action as the Yamaha P155. In other words, they both use the GH action keyboard.

These are one of Yamaha’s best keys and are a significant improvement over the GHS that are in the cheaper models. Despite this, I feel that the CP33 has heavier keys.

grand piano sound

It might be my imagination, but after trying the two digital pianos for about an hour, I just can’t help but thinking that the CP33 had heavier keys. Take that into consideration.

Some people prefer heavier ones. Some prefer lighter ones. Regardless, the keys overall are very impressive (better than the Casio models and better than cheaper Yamaha models). You won’t be disappointed with them.

As for the grand piano sound, the Yamaha CP33 has 3 sampling layers as opposed to the 4 sampling layers in the P155.

If you’re looking for an extremely pure piano sound to keep at home, you should look at the P155. However, one extra sampling layer is unnoticeable for most people, and as such, the CP33′s sound is also great.

You shouldn’t worry about the technical aspects too much as both feel and sound great. However, as I’ve already stated, if you need the absolute best grand piano sound and you will be strictly playing at home, don’t buy this and research the P155.

One minor complaint is that the looping samples are noticeable when you hold down the key for a long time. This won’t be a problem if you play fast passages. It’s also not as noticeable as most other models. However, if this will bother you, then you would need to look at more expensive models.

Yamaha CP33: Features

First, the Yamaha CP33 does not have built-in speakers. Don’t be alarmed. This is normal in stage pianos. You might be wondering, “Why?” or “What makes this better than the P155 then?” Well, they don’t have speakers because stage pianos use external speakers all the time.

Nobody is going to perform on stage with built-in speakers. That’s ridiculous. Speakers are just a hassle to have because they make the digital piano itself heavier for no reason. Simply put, the speakers will go unused.

Also, neither the P155 or CP33 is better than the other. They are similar digital pianos used for different purposes. Despite having no speakers or “only” 3 sampling layers, the CP33 have other advantages that attract a lot of other buyers.

The Yamaha CP33 has a better user interface. It’s best to demonstrate this with an example. Nobody that performs on stage will look at the digital piano, press down, press down, press right, press down, and then choose the instrument (slight exaggeration). Instead, performers use sliders or presets. In other words, at the push of a button, you can play the electric piano or some other instrument. Simple. Easy. Perfect.

Also, there are certain functions in the CP33 that you can use with just a wheel or a knob. You don’t have to go through the hassle of going through the entire menu. Everything about it is just easy-to-use and quick, which makes it a great stage piano choice.

The CP33 has wheels that can adjust/change the pitch and mod. Performers tend to use them, and if you do, then you’ll need this digital piano. This, however, is not necessary for those that just like to focus on the grand piano.

It has weaker polyphony and fewer voices. In pure numbers, the CP33 has a 64-note polyphony as opposed to the 128-note polyphony on the P155. This might turn you off from the CP33, but let me just say that most players will not need more than a 64-note polyphony.

This is only a problem if you actually know what you’ll need more, which I’m guessing is not the case for you. It also has 14 voices (2 variations of each voice) as opposed to the 17 voices on the P155 (voices are Yamaha’s way of saying instrumental sounds). Nevertheless, the organs, electric pianos, and other sounds all sound beautiful. It has a very high-quality tone, perfect for performing.

Yamaha CP33: Portability, Durability, and…Looks

The Yamaha CP33 isn’t portable as in the sense that you can just carry it around and play it anywhere. It does weigh 39.7 pounds. However, this is light enough to be portable for performing reasons.

Yamaha digital pianos are known for their durability. You’ll immediately notice that it is made of high-quality material and not cheap plastic. It also has this cool matte black color as opposed to the furniture-look of the P155. Once again, the looks will come down to personal preference (if it matters at all to you).

What do Other Reviewers Say?

  •     “If you want a great piano sound and feel, get this keyboard.”
  •     “Using an external recording device I’ve made much nicer piano recordings from the CP33 than I ever got from my acoustic.”


With an extremely stage-friendly interface and features, the Yamaha CP33 is the perfect choice for those that perform on stage. Although the grand piano sound may have one less sampling layer than the Yamaha P155, people will generally not be able to notice that. Get the P155 if you want the best grand piano sound.
